wtf? Why do I get downvoted? Could the downvoter explain please. Again, insteat of being able to just select a parent on the existence of a child, why not be able to select any element on the existence of another element? Change the background of a body > div if there is only one child in a list body > ul > li:only-child for example. body > div /if/ body > ul > li:only-child { background:green; } Or replace /if/ with :: or $ or whatever.

I'm not sure you understand what /op/ does. It's a reference indirection going through an IDREF type: * It finds whatever elements are before the operator * It gets the value of the operator's attribute (or type IDREF), ~ storing it in $ID * it combines the selector after it with the root being extended with `[id=$ID]` `/if/` would get the value of the attribute `if` and try to find an element with that value as its id.

  Again, what I care about is not the syntax but the functionality. If you want write it as body > div:if(body > ul > li:only-child) { background:green } body > div:not(body > ul > li:only-child) { background:green } which may or may not already work in CSS3.

    > Again, what I care about is not the syntax but the functionality. Issue here is that you're talking about this using syntax for something which has absolutely no relation. Which is a tad confusing. No, what you want does not work in CSS, you can't make a selector conditional on a second completely unrelated selector (you probably can in XPath, although I'm sure your colleagues will soon look to end your life if you do)

      Could you explain why? Let's say you have a clickable element and want to display a status text on hover. The status texts are loaded in some divs somewhere else on the page. You would need JS to catch onhover and then swap the display:hidden to block or whatever. Why would anybody look to "end my life" if that was possible? div.status > span:on(div.clickme > a:hover) { display:block; } Why would that be bad?

        > Why would that be bad? It's "action at a distance", it's very, very hard to understand and debug what happens.

        (1) You mean like when you do the same thing with Javascript? Why its okay then? (2) If you alter a parent element with CSS that's "action on a distance" as well. Your argument is not very convincing.
